+ Work has now been finished on a new ihost written in C. This has
+ been in the pipeline for a long time, and we're glad to finally
+ see an efficient native host! Credit goes to our new developer
+ <a href="/who.shtml">Pete</a>. Until we update the downloads
+ pages you can download the new ihost

- All i-scream components now function to initial
- design parameters and our system is regarded to be complete.
- <b><a href="worddocs/">Documentation</a></b> is available to assist third party programmers
- in producing Hosts for use with the i-scream server.
- Our progress during the project can be found in the meeting minutes.
- Code is viewable via <a href="http://raptor.ukc.ac.uk/~tdb1/cgi-bin/viewcvs.cgi">CVS</a> to local users users only.

+ We've finally put the finishing touches to the new
+ <a href="http://rrdtool.eu.org">RRDtool</a> based graphing system.
+ It's working well, and has done away with the MySQL database
+ backend which took up far too many resources. This new system
+ generates the graphs in a more realtime nature, allowing more
+ flexible graphs to be generated. This is currently only available
+ through <a href="http://www.i-scream.org.uk/cgi-bin/cvs/viewcvs.cgi/cms/source/reports/rrdgraphing/">
+ CVS</a>.

- Our current host development allows us to pass machine statistics
- to our distributed filter arrangement, which then processes the
- data and stores it for later use. An example of such use is the
- historical report generator which produces graphs of machine
- usage over periods of time. A real-time
- client is also available (Conient) and alert information can be
- displayed to the public via dynamic web pages.

+ <b>Extending monitoring facilites</b><br><br>
+ <a href="screenshots/"><img border="0" src="screenshots/thumbnail-reports-raptor-load15.gif" width="100" height="107" align="left"></a>
+ Work is continuing, in conjunction with the new ihost, to extend
+ the range of i-scream's monitoring. Currently we are adding new
+ features to more accurately monitoring memory and swap usage,
+ along with more disk statistics. We are also planning to improve
+ the rather basic service monitors which are currently in place.
+ There are also many more subtle changes that need to be made to
+ improve the reliability and usefulness of i-scream's monitoring.

+ <b>Server security</b><br><br>
+ Security was something mostly overlooked in the original stage
+ of this project (due to the academic nature of the work). However,
+ once in production use this has become an issue, and is being
+ addressed. Initially the plan is to lock down the external points
+ of access (TCP & UDP) in the server to specific hosts. In the
+ longer term, encryption of data would be nice, but would take a
+ lot more time and work.

+ <b>Testing and Development</b><br><br>
+ <a href="screenshots/"><img border="0" src="screenshots/thumbnail-winhost-main.gif" width="100" height="62" align="right"></a>
+ The i-scream system is being tested and developed within the
+ Univeristy of Kent Computer Science department by the Systems
+ Group. This has led to many bug fixes and minor feature
+ enhancements, and will hopefully help to aid the long term
+ development of the system.

The i-scream Distributed Central Monitoring System started off as
- a final year project for a group of <a href="http://www.cs.ukc.ac.uk">Computer Science</a> students at
- the <a href="http://www.ukc.ac.uk">University of Kent at Canterbury</a>, UK.
- The project deadline was 4pm on 29th March 2001. Most of the group
- met very early that morning to compile the project into five
- lever arch folders. The project, consisting of source code, user,
- maintenance and other documents, was handed in at 3pm. The CVS
- repository was tagged to signify the project's completion, however,
- the project is still being developed by the <a href="acknowledgments.shtml">core development team</a>
- as we have found the system to be very useful in practice. We would
- love to hear of ideas for extra features that we may include in the
- next builds.

The name <i>i-scream</i> arose from a meeting whereupon one member
of the <a href="acknowledgements.shtml">development team</a> felt a strange urge to draw an ice cream on the discussion board.
It later became apparent that we had no name for our project (other
Copyright issues immediately ruled out anything involving Mr Whippy,
so we had to settle for <i>i-scream</i>. And thus, we were left with a cunning
play on words - it still sounded like <i>ice cream</i>, yet also
- served as a functional decription of our system - namely, one which
+ served as a functional description of our system - namely, one which
screams at somebody if something has gone wrong...
